I have to work on my laptop more often because of school and I have extreme pain on my finger tendons (?) What can I do to make it less painful? Cool? To warm?
Operate the mouse with the other hand.
The left hand is completely uncoordinated for me 😂
It is perfectly normal. However, this quickly gets better, especially if you also use your left hand for training for other activities. You will see that it is even fun.
Both hands are twins. One is boss and the other assistant, but assistant can be very learnable.
Ask the boss hand to help the assistant hand learn to use the mouse. - You may be surprised at how good it is then.
Remember not to overwhelm the hand, it does not become the boss, but remains an assistant.
